ALBERT B. DISS, OF NEWARK, NEW

JERSEY, .ASSIG-NOR TO UNIVERSAL CASTER &

FOUNDRY COMPANY, OF NEW YORK, N. Y., A CORPORATION OF NEW JERSEY.

GAS'I'ER.

To all whom it may concern Be it known that I, ALBERT B. DISS, aresident of Newark, in the State of New Jersey, manufacturer, haveinvented certain new and useful Improvements in Casters, of which thefollowing is a specification, accompanied by drawings.

The invention relates particularly to casters for wooden furniture legs,but the use is not restricted to wooden legs.

The object of the invention is to provide a caster having an extremelysimple, strong, and reliable, but inexpensive, construction of thecaster jaws, which is particularly suitable for casters havingnon-rotary pins driven into the leg and caster jaws swiveling thereon.

The novel features will stood from the following claims.

In the drawings, Figure 1 is a side elevation of a caster embodying theimprovement and applied to a wooden leg, which is shown incross-section; Fig. 2 is an elevation of the same caster at rightangles; Fig. 3 is a detail view, showing the caster jaws in centralsection; Fig. 4 is an inclined view of the caster jaws with the pinremoved; Fig. 5 is a view of the blank from which the jaws are made.

In the drawings, the leg is shown in Fig. 1, in section and marked B.The pin C of the caster is secured by being driven into a suitable holebored to fit it in the leg. The caster jaws D swivel upon the projectinglower portion of the pin. The pin is provided with a collar C, whichrests upon the jaws and carries the weight of the leg, and a head C atits lower end, which secures the jaws on the pin.

The caster jaws are formed of a sheetmetal blank, as shown in Fig. 5.The blank is slitted, as at D, and the portion 1) above the slit is benttoward the caster wheel to form an upper semi-circular or partialbearing on one side only of the pin. The portion D beneath the silt issimilarly bent in the opposite direction, forming a lower semi-circularbend or partial bearing on the opposite side of the pin, but the lowerportion of this lower bearing D has two ears or extensions 1), which arebent around the pin and form a complete tubular continuation of thelower hearing at the lower end. The blank is also bent upon two verticalbe readily underdescription and Specification of Letters Patent.

lines to form the two arms or sides D of the caster jaws, as shown.

I here make no claim broadly to forming half bearings in caster jaws bymeans of slits and semi-circular portions, but it will be seen that inaddition to the two semicircular bearings, well adapted to preventtilting of the caster jaws in the one direction under the weight of theleg, this caster has its pin completely encircled at the lower end bythe metal of the caster jaw, thus aflording a third bearing to preventtilting in the opposite direction, which bearing is formed by the twoends D of the tubular extension of the lower semi-circular bearing D.This third bearing is thus formed in such a manner that the lower semicircular bearing itself continues all the way down to the lowestpossible point of bearing against the pin, giving the maximum length ofbearmg and consequent strength of the caster jaws for any given lengthof contact between the pin and the jaws. It will be seen that the upwardpressure 011 the caster wheel WV forces the upper bearing against thepin in one direction (away from the caster wheel) and forces the lowerbearing against the pin in the opposite direction (toward the casterwheel), and since in this improved construction the lower bearing Dextends all the way down to the head C of the pin, it gives the maximumlength and strength of bearing on the sides and at the points ofgreatest strain between the jaws and the pin.

I claim and desire to secure the following:

1. A caster having a caster wheel, jaws and pin, and in which the casteraws are of sheet metal slitted and spread open for the pin between twosubstantially semicircular oppositely-bent bearing portions for the pinwhich bear on opposite sides of the pin, and one of the said bearingportions having a continuation at its end remote from the other bearingwhich substantially encircles the pin and is adapted from all sides.

2. A caster having a caster wheel, jaws and pin, the said jawscomprising a piece of sheet metal slitted and spread open for the pinbetween two oppositely bent portions which form upper and lower partialbearings acting on opposite sides of the pin, the said lower bearingbeing on the side away from the caster wheel and being provided with anextension substantially encircling to bear on the pin the pin, the saidjaws also having an upper bearing for the pin on the same side as thecaster Wheel.
